IMPORTANT: This is a longstanding flake for multiple releases that is now no longer allowed to flake in 4.20. (see this conversation) Do not look for a recent change that caused this. Note that they are believed to be rock solid on upstream kube, this handful of tests will need to be examined for why they fail on openshift and fixed for 4.20.

Note that these two tests appear to now flake WAY more than 4.17, both in 4.19 and 4.20.
